2010 Subaru Exiga Camshaft Sensor: What It Does and When to Replace It

Technical sources confirm the 2010 Subaru Exiga does use a camshaft position sensor. Subaru’s YA-series Exiga workshop manual (Fuji Heavy Industries, Engine section, EJ-series), Subaru’s STIS diagnostic documentation for DTCs P0340/P0341/P0345, and the Subaru electronic parts catalogue listing (e.g., camshaft position sensor, often catalogued under 22056AA061 for YA variants) all identify a camshaft sensor fitted to 2010 Exiga models. Depending on engine variant, there may be at least one sensor, and some versions run a sensor per bank to support AVCS.

On the 2010 Subaru Exiga, the camshaft sensor tells the ECU exactly where the camshaft sits in relation to the crank. That’s critical for clean starts, sequential fuel injection, ignition timing, and for engines with AVCS (Subaru’s variable valve timing), which rely on accurate cam position to advance or retard timing on the fly. When the sensor goes on the fritz, owners might notice longer cranking, a rough idle, flat spots, sluggish performance, or the check engine light with codes like P0340/P0341. Fuel economy can take a hit, and in some cases the car may drop into a limp mode.

This sensor isn’t a regular service item, but a quick look during scheduled maintenance goes a long way. Check the plug and loom for brittle insulation, oil wicking into the connector, or corrosion, especially around the cylinder head area under the plastic covers. If replacing, use a quality sensor (genuine or reputable aftermarket) and a fresh O-ring. A light smear of clean engine oil on the O-ring helps it seat without nicking. The retaining bolt is a small one—nip it up to the specified torque in the factory manual rather than swinging on a long spanner. After fitting, clear the codes and confirm cam/crank sync with a scan tool, if the fault returns, inspect the trigger wheel and wiring.

There’s no set kilometre interval for replacement—fit a new sensor when there are symptoms or relevant fault codes. For location, most 2010 Exiga engines place the cam sensor on the cylinder head near the cam sprocket under the front cover, some variants have one per bank. If in doubt, verify against the VIN in the parts catalogue or workshop manual.

• Common signs it’s due: hard starting, rough idle, poor fuel use, misfire-like stumble, DTCs P0340/P0341/P0345.
• Good practice: inspect wiring/connectors, replace the O-ring, and follow factory torque specs.

FAQs

Where is the camshaft sensor on a 2010 Subaru Exiga?
It’s typically mounted on the cylinder head near the cam sprocket under the front plastic cover. Many Exiga EJ variants have at least one sensor on the left-hand bank, some versions use a sensor per bank to support AVCS. Access is usually under the bonnet after removing the engine cover.

Can the camshaft sensor be cleaned, or should it just be replaced?
You can gently wipe the tip and clean the connector if there’s light grime or oil. If the car still throws cam sensor codes or shows sync issues after that, the reliable fix is replacement, as internal sensor faults can’t be repaired.

Is it safe to drive with a failing camshaft sensor?
Short trips may be possible, but it’s not ideal. A dodgy sensor can cause hard starts, stalling, or poor running, and prolonged misfires risk damaging the catalytic converter. Best to sort it sooner rather than later.
